ALAMEDA — The Raiders will interview Denver Broncos defensive coordinator Jack Del Rio Tuesday for the position of head coach, the Denver Post reported.

The Broncos lost 24-13 to the Indianapolis Colts, making Del Rio available for interviews. A first interview with Del Rio conducted in the Denver area by owner Mark Davis took place during Denver’s playoff bye week.

Del Rio has not met yet with general manager Reggie McKenzie or Hall of Fame coach John Madden, who has served as an advisor in some interviews on Davis’ behalf.

Del Rio is a former Hayward High star who is said by the NFL Network to be serious about wanting to coach the Raiders.

As of 9 p.m. Monday night, the only Raiders coach under contract will be interim head coach Tony Sparano. The rest of the Oakland staff was working on the last year of their deals.

With Rex Ryan announced as the head coach in Buffalo Monday, the game of musical chairs involving assistants will begin. The longer the Raiders wait to select a head coach, the more assistants who receive jobs elsewhere.

Four other teams — Atlanta, San Francisco, the New York Jets and Chicago Bears — have yet to name a head coach along with the Raiders.

Raiders defensive line coach Terrell Williams has accepted a job at the University of Florida, and quarterbacks coach John DeFilippo reportedly will interview with the Cleveland Browns for the offensive coordinator position which came open when Kyle Shanahan was released from his contract.

Two candidates who received preliminary interviews with the Raiders and McKenzie — Seattle offensive coordinator Darrell Bevell and Indianapolis offensive coordinator Pep Hamilton — are off limits until their teams are out of the playoffs.
